接收文件並洗牌

Question

之間的所有中間字母我需要拿出一個文件並洗牌每個單詞的中間字母，但我無法洗牌第一個和最後一個字母，而且我只能洗牌超過3個字符的單詞。我想我可以找出一種方法來打亂他們，如果我可以把每個單詞放在他們自己的單獨列表中，所有的字母都是分開的。任何幫助，將不勝感激。謝謝。

Answer 1

text = "Take in a file and shuffle all the middle letters in between" 

words = text.split() 

def shuffle(word): 
    # get your word as a list 
    word = list(word) 

    # perform the shuffle operation 

    # return the list as a string 
    word = ''.join(word) 

    return word 

for word in words: 
    if len(word) > 3: 
     print word[0] + ' ' + shuffle(word[1:-1]) + ' ' + word[-1] 
    else: 
     print word 

有意不實施洗牌算法。

Answer 2

看看random.shuffle。它將一個列表對象洗牌，這似乎是你正在瞄準的目標。你可以做這樣的事情洗牌周圍

`

def scramble(word): 

    output = list(word[1:-1]) 
    random.shuffle(output) 
    output.append(word[-1]) 
    return word[0] + "".join(output)` 

字母只記得導入隨機

Answer 3

#with open("words.txt",'w') as f: 
# f.write("one two three four five\nsix seven eight nine") 

def get_words(f): 
    for line in f: 
     for word in line.split(): 
      yield word 

import random 
def shuffle_word(word): 
    if len(word)>3: 
     word=list(word) 
     middle=word[1:-1] 
     random.shuffle(middle) 
     word[1:-1]=middle 
     word="".join(word) 
    return word 

with open("words.txt") as f: 
    #print list(get_words(f)) 
    #['one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine'] 
    #print map(shuffle_word,get_words(f)) 
    #['one', 'two', 'trhee', 'four', 'fvie', 'six', 'sveen', 'eihgt', 'nnie'] 
    import tempfile 
    with tempfile.NamedTemporaryFile(delete=False) as tmp: 
     tmp.write(" ".join(map(shuffle_word,get_words(f)))) 
     fname=tmp.name 

import shutil 
shutil.move(fname,"words.txt")
